4X4.chevy.trucks Diagnostic Course: Apprenticeship Advisory:
This is a selfpaced course designed to allow for each poster to proceed to the next step at a rate that is conducive to their own schedule and brain wave functions. Aprentice's should feel free to challenge any or all diagnostic steps as they wish. This course has been formatted in a step by step instructional layout that requires patients, minimal skill level, honest feedback, and willingness to accept sharp criticism and rebute from seansoned posters, by the Apprentice initiating the Symptom for Study. As a selfpaced format, said Apprentice is solely responsible for length of diagnostic time. Also, Apprentice retains sole discretion for accepting or dismissing any or all reccomended diagnostic proceedures. However, Apprentice is hereby notified that deviating from the assigned diagnostic steps may result in flaming, redicule, blatant performance evaluations, and other personal attacks that the more seasoned posters feel may be warranted. With this in mind, the NG looks forward to your successfull graduation in this course study.
